Title: Resilient-cantilever mounting of impact receiving members utilizing flexible suspension
IPC: F16D27/105
Filed: 1968-03-29
Abstract: 1,217,580. Springs; controlling clutches. BURROUGHS CORP. 29 March, 1968 [21 April, 1967], No. 15273/68. Headings F2L and F2S. [Also in Division H1] A leaf spring 48 connected as shown to a rigid arm 28 constitutes a combined clutch-operating means and shock absorber. The leaf spring at its end opposite the arm 22 is held in a clamp comprising the members 26 and 29 the effect of which is that a length T, Fig. 3, of the leaf is twistable about the longitudinal axis of the leaf and a greater length A is bendable in a plane parallel to the broadsides of the leaf. The twisting deflection provides a resiliently biased pivot for the arm 28 which is deflectable by an electromagnet 34 (see Division H1) to move the arm into and out of engagement with a projection 20 on a clutch mechanism 14 coupling two shafts 10, 12. The clutch (Fig. 5, not shown) is of the kind in which a coil spring (17) encircles the shafts and the projection 20 controls the coupling of this spring to the shafts. Fig. 2 shows the engaged state of the clutch: the arm 28, when moved into the path of projection 20 will disengage the clutch. When this occurs, the impact of projection 20 on the end of arm 28 constitutes a shock which must be absorbed. This is achieved by the bending of leaf 48 in the above mentioned plane, the spring having considerable stiffness in this mode of bending.
